This manuscript, divided into two parts, provides a contextual and historiographical analysis of Edwin Arthur Burtt's classic The Metaphysical Foundations of Modern Physical Science. My discussion corroborates the sparse technical literature on Burtt (Moriarty 1994;Villemaire 2002), positioning his work in the aftermath of American idealism and the rise of realist, pragmatist and naturalist alternatives. However, I depart from the existing interpretations both in content and focus. Disagreeing with Moriarty, I maintain that Burtt's Metaphysical Foundations is not an idealist work. Moreover, I provide an alternative to Villemaire's mainly Deweyite/pragmatist reading, emphasizing the import of new realism and naturalism. Burtt's historical thesis should not be viewed as outlining a systematic philosophical position, but rather as a (coherent) culmination of numerous philosophical problematics. To support my conclusion, I provide a substantial summary of Burtt's text alongside a contextual analysis of the philosophical issues that preoccupied his teachers and peers in Columbia's philosophy department. I conclude with a historiographical section, rendering explicit the connections between Burtt's understanding of the scientific revolution, and his distinctive early 20 th century American intellectual context.
